Which is true about secondary consumers in an ecosystem?

Question

They are eaten by primary consumers.

They eat only plants.

They are smaller n weaker than are primary consumers.

They are fewer in number than are primary consumers.

They contain the greatest total biomass in the system.

Answer 1

The answer is  They are fewer in number than primary consumers. This is vital for a food chain to function properly. A good example of this would be a rabbit and a hawk. The rabbit is the primary consumer. The hawk is the secondary consumer. In numbers this would be rabbits number 30, hawks number 3. This is a balance for both animals. If there were 30 rabbits and 25 hawks then the food chain would stop very quick due to the lack of food for the secondary consumer.

Answer 2

they are fewer in number....
